Description

Technical Field

[0001] This invention relates to the technical field of spray painting equipment, and in particular to a highly efficient and environmentally friendly metal spray painting device. Background Technology

[0002] To prevent metal oxidation and corrosion, metals need to be painted to form an isolation layer that prevents corrosive media from penetrating.

[0003] Chinese patent document CN114682425A discloses an environmentally friendly surface painting device for metal pipes. A transmission wheel is rotatably connected to the upper surface of the housing, a slide rail is fixedly connected inside the housing, a base is fixedly connected inside the housing and inside the slide rail, a fixed shell is fixedly connected to the upper surface of the base, a slide frame is slidably connected inside the slide rail, and a slider is slidably connected inside the slide rail and below the slide frame. This device uses a cleaning brush to clean the surface of the metal pipe before painting, removing impurities from the outer surface of the metal pipe to prevent impurities from affecting the uniformity of the paint spraying. Additionally, an air supply pipe can be used to paint the metal pipe, accelerating the drying of the paint on the outer surface. However, the following shortcomings still exist.

[0004] This patent uses a cleaning brush to clean metal surfaces, but there is a certain distance between the bristles on the cleaning brush. Even with multiple cleaning brushes, it is difficult to clean the metal surface completely. Furthermore, when painting metal, it is impossible to recover the paint sprayed outside the metal, which wastes resources and increases operating costs. Summary of the Invention

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. This invention, through the design of an air outlet pipe, a transfer pipe, and a water storage tank, allows water injected into the storage tank to be rapidly sprayed onto the metal plate under the continuously increasing air pressure within the tank, thus rinsing it. Simultaneously, a water removal mechanism is incorporated, utilizing the airflow from the air outlet pipe to control two cross-shaped scrapers and rubber pads to rotate in opposite directions, scraping away water stains and impurities from the metal plate, facilitating cleaning. Furthermore, the inclusion of a water absorption mechanism and a heating box allows the heating box to compress as the metal plate passes through it, enabling part of the heating box to penetrate into the recesses on the metal plate surface and absorb any remaining water stains, preventing interference with subsequent painting. As the metal plate passes through the heating box, the hot air further removes moisture from its surface, ensuring thorough cleaning and providing temporary heating to accelerate the drying of the paint.

[0022] 2. By setting up structures such as triangular airbags and paint scrapers, the triangular airbags will fit tightly against the side of the metal plate after inflation to receive the paint sprayed outside the metal plate. After the work is completed, the paint scraper is controlled by the cylinder to move down, compressing the triangular airbags while scraping off the paint on the inclined surface of the triangular airbags. The paint can then fall through the opening slot into the collection slot for collection, which is convenient for subsequent recycling through the discharge pipe.

[0023] 3. By setting up structures such as sealing airbag one and sealing airbag two, it is convenient to seal the space inside the shell where painting work is carried out, so as to prevent some of the atomized paint from circulating to the outside air and polluting the air and harming the health of the workers. In addition, by setting up inclined airbags, it is convenient to allow the paint surface of the metal plate to be dried a second time, so as to prevent the paint on the metal plate from being rubbed off by sealing airbag two when the metal plate leaves, thus ensuring the integrity of the paint surface on the metal plate.

[0035] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0036] Example 1

[0037] like Figure 1-8As shown, this embodiment discloses a high-efficiency and environmentally friendly metal spraying device, including a housing 1. The left and right sides of the bottom wall of the inner cavity of the housing 1 are respectively provided with a first mounting groove 112 and a second mounting groove 122. The first mounting groove 112 and the second mounting groove 122 are respectively provided with a first conveyor mechanism 15 and a second conveyor mechanism 16 for transporting metal plates. Both the first conveyor mechanism 15 and the second conveyor mechanism 16 are conveyor belts composed of two rotating rollers and a support plate, controlled and driven by a motor installed at the rear end of the housing 1 through a coupling. This is prior art, therefore... Without going into too much detail, mounting grooves 3 10 are provided in the middle of the front and rear inner side walls of the outer shell 1. The two mounting grooves 3 10 are equipped with a ventilation box 2. The upper end of the ventilation box 2 extends to the outside of the outer shell 1 and is equipped with an air inlet pipe 22 that communicates with the ventilation box 2. Air is introduced into the ventilation box 2 through the air inlet pipe 22 and then guided to cause multiple airbags in the outer shell 1 to inflate simultaneously, sealing the outer shell 1 and preventing some of the atomized paint from flowing to the outside through the air when painting metal, thus polluting the environment and harming the health of workers.

[0038] For details, please refer to Figure 3 The lower right end of the vent box 2 is equipped with a water-absorbing mechanism 6 for removing moisture from the surface of the metal plate, preventing residual water stains on the metal plate from affecting the painting effect. The lower end of the vent box 2 is equipped with a heating box 27 that communicates with its inner cavity. The lower end of the heating box 27 has a hot air duct that communicates with its inner cavity. Inside the heating box 27 is an electric heating wire located directly above the hot air duct. The air flowing inside the vent box 2 is heated by the electric heating wire and then directly sprayed onto the metal plate through the hot air duct to remove residual water stains. Moisture is used to heat the metal plate to accelerate the drying speed of the subsequent paint. The two opening slots 121 are equipped with a water tank 5 fixedly connected to the ventilation box 2. The water tank 5 is located above the water suction mechanism 6. The lower part of the water tank 5 is equipped with a water removal mechanism 7 for cleaning. The water removal mechanism 7 removes most of the water stains and impurities to avoid affecting the subsequent painting process. At the same time, it reduces the pressure of the water suction mechanism 6 and reduces the water absorption of the sponge sleeve 67, thereby extending the working time of the sponge sleeve 67.

[0039] For details, please refer to Figure 4 The upper part of the water tank 5, away from the ventilation box 2, is provided with a water inlet pipe 51 that communicates with the water tank 5. The lower end of the water tank 5 is provided with several water outlet holes that communicate with the water tank 5. The lower right part of the water tank 5 is provided with a shield curtain 52 to prevent water from splashing outward. A large amount of water is injected into the water tank 5 through the water inlet pipe 51, and then the water flows out through the water outlet holes, splashing onto the metal plate to rinse it. The lower end of the shield curtain 52 is at the same horizontal height as the upper end of the conveying mechanism 16, so as to avoid water splashing outside the device and wetting the clothes of the surrounding staff.

[0040] For details, please refer to Figure 5 The bottom wall of the inner cavity of the water storage tank 5 is an inclined surface with the left side higher than the right side, so that the water can flow out as much as possible after a single operation, reducing the residue and thus reducing the probability of corrosion of the water storage tank 5, thereby extending the service life of the device.

[0041] For details, please refer to Figure 5-6 The right end of the vent box 2 is provided with an air outlet pipe 25 that communicates with the inner cavity of the vent box 2. The right side of the inner surface of the air outlet pipe 25 is provided with two guide plates 251 so that some airflow can be guided by the inclined surface of the guide plate 251 to flow into the transfer pipe 26 as much as possible, so that the air pressure in the inner cavity of the water storage tank 5 is always kept at a high level. The outer surface of the air outlet pipe 25 is provided with two transfer pipes 26 that communicate with the inner cavity of the water storage tank 5, so as to introduce air into the inner cavity of the water storage tank 5, increase the air pressure in the water storage tank 5, thereby reversely squeezing the water flow and accelerating the downward flow speed of the water flow through the water outlet, so that the water flow can quickly impact the metal plate, remove mud and other impurities adhering to the metal plate, thereby improving the subsequent painting effect. The inside of the water storage tank 5 is provided with an installation box 53 to prevent water flow interference.

[0042] For details, please refer to Figure 5 The water removal mechanism 7 includes two rotating mechanisms 77 rotatably connected to the lower end of the water storage tank 5. The lower end of each of the two rotating mechanisms 77 is provided with a cross-shaped scraper 78. The four branches of the two cross-shaped scrapers 78 are staggered when rotating to scrape away water stains and impurities on the metal plate as much as possible, so as to avoid affecting subsequent painting. The lower end of the two cross-shaped scrapers 78 is provided with a rubber pad 79 to reduce the gap between the cross-shaped scraper 78 and the metal plate and reduce water stain residue. The upper ends of the two rotating mechanisms 77 penetrate through the bottom of the water storage tank 5 and are rotatably connected to the top wall of the inner cavity of the mounting box 53.

[0043] One of the rotating mechanisms 77 has a spur gear 2 75 on its upper outer surface. A spur gear 1 73 meshes with the outer surface of the spur gear 2 75. The spur gear 1 73 and spur gear 2 75 cause one of the rotating mechanisms 77 to rotate in the opposite direction to the rotating rod 71. The upper end of the spur gear 1 73 has a rotating rod 71 that passes through the mounting box 53 and extends to the outside of the water tank 5. The outer surface of the rotating rod 71 located outside the water tank 5 has multiple rectangular frames 72 evenly distributed on the right side of the air outlet pipe 25. That is, at least one rectangular frame 72 is located directly to the right of the air outlet pipe 25, so that the airflow from the air outlet pipe 25 can drive the rotating rod 71 to rotate. Specifically, as shown... Figure 9As shown in the figure, the positional relationship between the air pipe 25, the rectangular frame 72, and the rotating rod 71 is clearly shown, so it will not be described in detail here. The inner side of the rectangular frame 72 is provided with an elastic membrane 721 for facilitating the use of wind power. The elastic membrane 721 will use the airflow ejected from the air pipe 25 to bulge outward as much as possible, so as to facilitate the use of the impact force brought by the airflow to drive the rotating rod 71 to rotate.

[0044] A belt 76 is provided on the outer surface of the rotating rod 71 located in the inner cavity of the mounting box 53 and the outer surface of one of the rotating mechanisms 77 located far from the rotating rod 71. The two rotating mechanisms 77 are rotated in opposite directions by using spur gear 1 73, spur gear 2 75 and belt 76. The two cross scrapers 78 and rubber pads 79 are rotated alternately to push away water stains and impurities on the metal plate. The water and impurities enter the collection tank 2 12 along the opening groove 2 121 and are finally discharged through the collection tank 2 12.

[0045] Specifically, the rotating mechanism 77 includes a rotating rod 771 rotatably connected to the mounting box 53 and a rotating rod 773 fixedly connected to the cross blade 78. The upper end of the rotating rod 773 is provided with a baffle 772, which facilitates the upward movement of the rotating rod 773 through the baffle 772. When the rotating rod 773 needs to move downward, it will automatically slide down using the weight of the cross blade 78, the rubber pad 79, and the rotating rod 773 itself. The upper end of the baffle 772 is provided with a regular hexagonal rod 774 slidably connected to the rotating rod 771. That is, there is a groove at the lower end of the baffle 772 for the regular hexagonal rod 774 to slide into the interior of the rotating rod 771, so that the rotating rod 773 can rotate together with the rotating rod 771 through the regular hexagonal rod 774, and can also move upward through the regular hexagonal rod 774 and the rotating rod 771.

[0046] Specifically, the rear end of the outer shell 1 is provided with an opening groove 3 19 that connects to the inner cavity of the outer shell 1, and the vertical cross-sectional dimension of the opening groove 3 19 is larger than the vertical cross-sectional dimension of the water absorption mechanism 6, that is, the entire water absorption mechanism 6 can be observed through the opening groove 3 19, thereby facilitating the replacement of the sponge sleeve 67.

[0047] For details, please refer to Figure 7-8The water absorption mechanism 6 includes a fixed block 61 fixedly connected to the ventilation box 2. The rear end of the fixed block 61 is provided with a rotating rod 62, and the rear end of the rotating rod 62 is provided with a knob 63. The front end of the rotating rod 62 extends into the interior of the fixed block 61 and is provided with a bevel gear 642. The interior of the fixed block 61 is threadedly connected to a threaded rod 641. The outer surface of the threaded rod 641 is provided with a bevel gear 643 rotatably connected to the fixed block 61. The bevel gear 643 meshes with the bevel gear 642. The rotating rod 62 and the bevel gear 642 can be rotated by rotating the knob 63. Then, the bevel gear 642 controls the threaded rod 641 to move up and down through the meshing bevel gear 643, thereby facilitating the control of the height of the sponge sleeve 67 so that the sponge sleeve 67 can always be tightly attached to the metal plate.

[0048] The lower end of the threaded rod 641 extends to the outside of the fixed block 61 and is provided with an adapter plate 64. The front and rear outer end walls of the adapter plate 64 are respectively provided with a connecting plate 65 and a connecting mechanism 66. The sponge sleeve 67 can be removed from the water absorption mechanism 6 for replacement through the connecting mechanism 66, so as to avoid the damp sponge sleeve 67 affecting the absorption of water stains remaining in the gaps on the surface of the metal plate. The ends of the connecting plate 65 and the connecting mechanism 66 that are close to each other are respectively provided with a first insert rod 651 and a second insert rod 663. The outer surfaces of the first insert rod 651 and the second insert rod 663 are provided with rollers. The rollers and the sponge sleeve 67 are moved down by rotating the knob 63 until the sponge sleeve 67 is compressed. The sponge sleeve 67 prevents the roller from moving further down. This serves two purposes: firstly, it allows the sponge sleeve 67 to rotate using the friction between the metal plate and the sponge sleeve 67, thus extending the working time of the sponge sleeve 67; secondly, it allows part of the sponge sleeve 67 located above the recess in the metal plate to penetrate into the recess and absorb water stains, preventing them from affecting the subsequent painting effect. In addition, the bottom of the outer surface of the roller is at the same horizontal level as the lower end of the connecting rod 68. When the roller can no longer move down, the lifting ring 69 is in close contact with the metal plate, so as to scrape away as much water stains as possible from the metal plate. The outer surface of the roller is provided with a sponge sleeve 67.

[0049] Specifically, the right end of the sponge sleeve 67 is provided with two connecting rods 68, and the right end of each connecting rod 68 is provided with a lifting ring 69 sleeved on the outside of the rotating rod 773. When the adapter plate 64 drives the sponge sleeve 67 to move upward, the connecting rods 68 and the lifting ring 69 will lift the baffle 772 and the rotating rod 773 to move upward together, so that the water absorption mechanism 6 and the water removal mechanism 7 can cooperate and adjust each other, reduce the operation steps, and improve the work efficiency.

[0050] For details, please refer to Figure 8The connecting mechanism 66 includes a connecting plate 661. The vertical cross-sectional dimensions of the connecting plate 661 are the same as those of the adapter plate 64, and the connecting plate 661 and the adapter plate 64 are at the same horizontal height. A rotating plate 662 is rotatably connected to the lower part of the connecting plate 661. The insertion rod 663, which is mounted on the connecting mechanism 66, is specifically mounted on the rotating plate 662 at the end near the connecting plate 65. A handle 664 is provided on the side of the rotating plate 662 away from the connecting plate 65 to facilitate pulling the connecting mechanism 66 outward, so that the insertion rod 663... 3. Separated from the roller, the adapter plate 64 has two grooves 646 at one end near the connecting mechanism 66. The inner front wall of each groove 646 is provided with a slide bar 645 and a spring 644 wrapped around the outside of the slide bar 645. The slide bar 645 extends to the outside of the adapter plate 64 and is slidably connected to the connecting plate 661. That is, the slide bar 645 is slidably connected to the inside of the connecting plate 661 to limit and support the connecting plate 661. A part of the spring 644 near the connecting plate 661 passes through the groove 646 and is fixedly connected to the connecting plate 661.

[0051] Therefore, the specific implementation method of this embodiment is as follows:

[0052] First, place the metal plate on the conveying mechanism 2 16 and conveying mechanism 15 inside the outer casing 1; then rotate the knob 63 to control the rotating rod 3 62 and bevel gear 1 642 to rotate, which drives the meshing bevel gear 2 643 to rotate, and controls the threaded rod 641 to move down the thread, so that the adapter plate 64 moves down to compress the sponge sleeve 67 until it can no longer move down. During the process of the adapter plate 64 moving down, the baffle 772 will lose the obstruction of the lifting ring 69, so that the rotating rod 2 773 moves down together under the influence of the cross scraper 78 and the weight of the rotating rod 2 773, until the baffle 772 is blocked by the lifting ring 69 again.

[0053] Then the metal plate is moved back to the conveying mechanism 16. The conveying mechanism 16 slowly transports the metal plate into the outer shell 1. Water is then injected into the water storage tank 5 through the water inlet pipe 51, and air is introduced into the air box 2 through the air inlet pipe 22. Then, part of the air is blown into the rectangular frame 72 and the elastic membrane 721 through the air outlet pipe 25, causing them to start rotating and controlling the water removal mechanism 7 to start working. The other part of the air will be guided by the guide plate 251 and enter the water storage tank 5 through the transfer pipe 26, increasing the air pressure in the water storage tank 5, thereby squeezing the water flow to quickly shoot through the water outlet hole onto the metal plate to rinse the metal plate.

[0054] During the rotation of the rectangular frame 72, the rotating rod 71 controls the rotation of the spur gear 73. The rotating rod 71 then controls the rotation of one of the rotating mechanisms 77 via the belt 76. The spur gear 73, in turn, controls the rotation of the other rotating mechanism 77 in the opposite direction via the meshing spur gear 75. This controls the two cross blades 78 and the rubber pad 79 to rotate in the opposite direction, scraping away water stains and impurities from the metal plate. When the metal plate moves onto the conveying mechanism 15, it squeezes the sponge sleeve 67, causing the roller and the sponge sleeve 67 to rotate, further absorbing any remaining water stains on the metal plate to avoid affecting the subsequent painting effect.

[0055] After the metal plate is painted and leaves the outer casing 1, reach into the outer casing 1 through the opening slot 3 19, grasp the handle 664, and pull the connecting mechanism 66 outward to separate the plug rod 2 663 from the roller. Finally, flip the rotating plate 662 upward to pull the roller out of the plug rod 1 651 and replace the damp sponge sleeve 67.

[0056] Example 2

[0057] This embodiment, based on Embodiment 1, adds a paint scraper 4, a second sealing airbag 17, and a first sealing airbag 21 to seal the device during the painting process, preventing atomized paint from drifting into the air and harming the health of nearby workers. Figure 2-3 and Figure 9-10 As shown, a material storage box is provided on the left side of the top wall of the inner cavity of the outer shell 1. Multiple nozzles are evenly distributed at the lower end of the material storage box, between two connecting plates 42. A feed pipe 8 communicating with the material storage box is provided at the upper front of the outer shell 1. A sealing airbag 21 communicating with the vent box 2 is provided at the lower left end of the vent box 2. Inflating the sealing airbag 21 seals the entrance to the painting workspace inside the outer shell 1, reducing paint leakage. A second sealing airbag 17 is provided on the left side of the top wall of the inner cavity of the outer shell 1 for sealing. Inflating the second sealing airbag 17 seals the outlet of the outer shell 1, reducing paint leakage. A third sealing airbag 17 is provided at the lower right end of the second sealing airbag 17. The inclined airbag 18, which connects the sealing airbag 2 17 and the inner cavity of the outer shell 1, allows excess air to be blown onto the metal plate after the sealing airbag 2 17 is inflated, thus accelerating the drying speed of the paint on the surface of the metal plate. In addition, the air inlet and outlet of the inclined airbag 18 are relatively narrow, much smaller than the air inlet of the sealing airbag 2 17, so that the sealing airbag 2 17 can inflate smoothly. The upper end of the sealing airbag 2 17 is provided with a ventilation pipe 24 that connects the sealing airbag 2 17 and the air inlet pipe 22. The air in the air inlet pipe 22 is diverted through the ventilation pipe 24 so that the sealing airbag 1 21 and the sealing airbag 2 17 can inflate almost simultaneously.

[0058] For details, please refer to Figure 2-3 The bottom walls of mounting slot 112 and mounting slot 212 are respectively provided with collection slot 11 and collection slot 212. Collection slot 11 is used to collect residual paint on the scraper 4, and collection slot 212 is used to collect water scraped off by the water removal mechanism 7. The front and rear inner side walls of collection slot 111 and collection slot 2121 are respectively provided with opening slot 111 and opening slot 2121. Paint and water flow into collection slot 111 and collection slot 212 through opening slot 111 and opening slot 2121 respectively. The upper middle part of the inner wall of the two opening slots 111 is provided with triangular airbags 3. After the triangular airbags 3 are inflated, they will stick tightly to the front and rear outer end faces of the metal plate to prevent paint from being sprayed onto the conveying mechanism 15, which is difficult to recover and clean. The two triangular airbags 3 are respectively provided with ventilation pipes 23 that pass through the two side walls of the outer shell 1 and are fixedly connected to the ventilation box 2.

[0059] For details, please refer to Figure 3 and Figure 9-10 The inner wall of the outer shell 1 is provided with two paint scraper 4 located in two opening slots 111 respectively. The width of the paint scraper 4 is smaller than the width of the opening slot 111, and the paint scraper 4 does not contact the inner wall of the opening slot 111. The left and right sides of the two paint scraper 4 are provided with connecting plates 42. The upper end of the outer shell 1 is provided with a cylinder 41. The output end of the cylinder 41 passes through the top wall of the outer shell 1 and is fixedly connected to one of the paint scraper 4. After the metal plate is painted, the output end of the cylinder 41 pushes one of the paint scraper 4 to move down. Then, the paint scraper 4 drives the other paint scraper 4 to move down together through the connecting plate 42 to squeeze the triangular air bag 3. The air in the triangular air bag 3 is squeezed back into the air box 2 through the air pipe 23. During the squeezing process, the paint scraper 4 will also scrape off the paint sprayed on the triangular air bag 3 due to its tilt and close contact with the triangular air bag 3, so that the paint enters the collection tank 111 through the opening slot 111.

[0060] Specifically, the lower side of the triangular airbag 3 connected in the opening slot 111 is at the same horizontal height as the conveying mechanism 15 and the conveying mechanism 2 16, so that after the triangular airbag 3 is inflated, the lower end of the triangular airbag 3 is still tightly attached to the conveying mechanism 2 16 and will not lift up to block the metal plate.

[0061] Specifically, the lower left and lower right parts of the outer casing 1 are respectively provided with a discharge pipe 13 and a water outlet pipe 14 connecting the first collection tank 11 and the second collection tank 12, so as to facilitate the final recycling of paint and wastewater from the first collection tank 11 and the second collection tank 12.

[0062] Therefore, the specific implementation method of this embodiment is as follows:

[0063] When the metal plate passes through the sealed airbag 21 and enters the painting workspace inside the outer casing 1, the cylinder 41 controls the scraper 4 to move downwards and squeeze the triangular airbag 3. First, the air in the triangular airbag 3 is pushed back into the ventilation box 2 through the ventilation pipe 23. When the metal plate moves between the two triangular airbags 3, the scraper 4 is then controlled to move upwards, causing the triangular airbags 3 to re-inflate and expand, squeezing the metal plate. Then, the metal plate is sprayed with paint through the nozzle. At this time, the metal plate utilizes the residual heat from being heated when passing through the heating box 27. To accelerate the drying of the paint surface, the airflow blown out by the inclined airbag 18 is used to further accelerate the drying of the paint surface of the metal plate, so as to prevent the paint on the metal plate from being rubbed off by the sealed airbag 17 when the metal plate leaves through the sealed airbag 2 17. After the work is completed, the cylinder 41 is started again to control the paint scraper 4 to move down and squeeze out the air in the triangular airbag 3, while scraping off the paint attached to the inclined surface of the triangular airbag 3, so that the paint enters the collection tank 11 through the opening groove 111, and finally leaves through the discharge pipe 13.
